EMMC4.5: Enable eMMC 4.5 Large Sector Size feature

BZ: 29677

According to eMMC Spec 4.5, enable large sector size feature
(4KB Native sector) can improve performance for eMMC device
bigger than 256GB.

To enable this feature, it needs to disable the emulation mode of
eMMC device first. Since the emulation mode disable is one-time
operation, it should be done by vendor or FW.

This patch will not disable emulation mode. It will just check
whether the eMMC device emulation mode has been disabled. If true,
then the driver will report kernel block layer with 4KB hardware
sector while keep 512B size block on eMMC bus. This is just what
the eMMC 4.5 Spec requires.

HDMI/PM: Port two HDMI hotplug patches from R2

BZ: 29595

The issue is tracked by BZ 19079, HDMI cable plug/unplugged not detected when
device is in S0 with Screen OFF. Jouni's two patches are ported to R3.

0001-hdmi-Fixes-for-hdmi-hotplug-detection.patch

Remove random control of HDMI rails around gfx driver. Power on is now
done in psb_intel_hdmi.c:mdfld_hdmi_init during boot up.

Global variable hdmi_state is not updated properly when display is
blanked. Fix this by updating hdmi_state in hdmi_do_hotplug_wq.

Also msic_irq should be type IRQF_NO_SUSPEND to ensure hpd interrupts
are not lost.

0002-hdmi-Implement-hdmi-cable-detection.patch

According to MSIC HDMI Integration Guide both, VCC330 and VHDMI, must
be enabled hotplug detection to work. This would cause unacceptable
power leak in S3 state -> Take approach to have hotplug detection
working only when device is not in S3. HDMI cable Plug in/out during
S3 is detected when waking up from S3. This allows powering off VCC330
and VHDMI during S3.

To implement this following changes are done in this patch:

Create dedicated freezeable workqueue for hotplug detection to ensure
ongoing detection is stopped before powering off HDMI rails on
suspend and resumed only when rails are powered on again.

Add mechanism to detect cable plug out during S3 when waking up.

v4l/atomisp: let pmu driver handle power island states

When atomisp is treated as real PCI device as it should be, ISP
often refuses to transition from D3hot to D0 state. This is likely
caused by an ordering problem where in resume PCI PM core restores
config space prior to calling pci_set_power_state and the driver's
rpm resume function. PMCSR in PCI PM cap is set to D0 from D3 but
refuses to transition possibly due to the fact that power islands
are still down for atomisp.

pmu driver such that the action is better coordinated.

REVERT ME: Define CONFIG_BOARD_MRFLD_HVP

BZ: 27386

Merrifield HVP platform only implemented 1 storage
host controller - eMMC0. Other 3 storage host controllers
are not existed in FPGA at all.

So the storage driver needs to know the board type
and prevent initialization to the 3 non-existen
host controllers if on the HVP board.

Actually, the board type macro CONFIG_BOARD_MRFLD_HVP
should be defined in arch/x86/Kconfig and enabled in
Merrifeld board specific configuration file. But now
these changes are not introduced yet. So this patch
just set it in mmc driver to make sure the storage
driver working on HVP board.

Once the macro defined and enabled in board specific
configuration file, this patch should be reverted.

ov8830: add partial support for getting sensor mode data

BZ: 27475

read using the ATOMISP_IOC_G_SENSOR_MODE_DATA private ioctl.
Currently sensor pixel clock, frame length and width (including

atomisp: fix num_flash_frames logic

BZ: 27997

Currently the num_flash_frames is used like a boolean. Let's make it usable on
a sequence of the frames.

A userspace could behave in the same way of following example:

video_request_flash(dev, num_flash_frames);
...
do {

if (!do_use_flash ||
buf.reserved == ATOMISP_FRAME_STATUS_FLASH_FAILED ||
buf.reserved == ATOMISP_FRAME_STATUS_FLASH_EXPOSED)
break;
do_qbuf(dev, &buf, ...); /* requeue buffer */
} while (1);

This patch also allows to ask for zero flash frames in case when we would like
to abort stalled operation.

BZ: 24993

There is a deadlock condition arising because of D0ix completion
interrupt not being handled in OS, because it is currently in Watch
dog timer interrupt handler and the d0ix completion interrupt handler

This causes the SCU PMU interrupt to be disabled until EOI interrupt
for d0ix completion is not reached.

Meanwhile OS has issued another PM command and times out because SCU
didn't handle it, and SCU is waiting for PM EOI interrupt to enable
PM interrupts.

We fix this by having a simple protocol between SCU and PMU driver

Opening the binder driver and sharing the file returned with

Prevent these crashes with the following changes:

  same binder_proc.
- After locking mmap_sem, check that the vma we want to access

- Use proc->tsk instead of current to get the files struct since

usb:gadget: drain ep0 when reset config

BZ: 25477

gadgets such as RNDIS, ACM and MTP use ep0 for command control. Thus, when resetting
config, it's necessary to make sure request pending on ep0 is drained.

rndis_command_complete doesn't check req->status before further processing, it's corrected
in the patch.

fix a NULL pointer issue of is_in macro in function ep_set_halt
